pub struct FallbackExtendedS<F>(_);

Trait Implementations

impl<F: Float> Semantics for FallbackExtendedS<F>

const BITS: usize

BITS: usize = 0

Total number of bits in the in-memory format.

const PRECISION: usize

PRECISION: usize = <Fallback<F>>::PRECISION

Number of bits in the significand. This includes the integer bit.

const MAX_EXP: ExpInt

MAX_EXP: ExpInt = <F>::MAX_EXP as ExpInt

The largest E such that 2E is representable; this matches the definition of IEEE 754.

const MIN_EXP: ExpInt

MIN_EXP: ExpInt = -<Self>::MAX_EXP + 1

The smallest E such that 2E is a normalized number; this matches the definition of IEEE 754.

const QNAN_BIT: usize

QNAN_BIT: usize = <Self>::PRECISION - 2

The significand bit that marks NaN as quiet.

const QNAN_SIGNIFICAND: u128

QNAN_SIGNIFICAND: u128 = 1 << <Self>::QNAN_BIT

The significand bitpattern to mark a NaN as quiet. NOTE: for X87DoubleExtended we need to set two bits instead of 2.
